Abstract

PURPOSE:To ensure fixed guantity transportation of granules during charging, by maintaining a pressure regulating valve at a prescribed opening, operating a supply tank exhaust regulating valve and controlling internal pressure in a transport tank to a fixed level, during the granules are charged in series from the pressurized transport tank to pressurized supply tank. CONSTITUTION:The pressures of tanks 2, 8 are equalized by an output of a quantity measuring device 21 in accordance with decrease of a residual qantity in the pressurized transport tank 8, and granules are charged from the tank 2 to the tank 8 through a charge valve 10. Here a control valve 25 and 27 are opened, and a selector circuit 31 is switched. In this way, a pressure reglating valve 15 for elevated pressure is not controlled but maintained at a prescribed opening. While an exhaust pressure regulating valve 28 is controlled by a pressure regulator 18. This causes a purge effect, and a discharge part 9 is fluidized. Then the control valve 25 is closed, and a control valve 22 is interruptedly opened, then the granules more than the regulated transport quantity are charged from the tank 2 to the tank 8. By this constitution, fixed quantity transportation can be continued even in a stage of charging the granules.

送方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a serial pressure continuous transport method for powder and granule materials, in particular, a powder supply tank is connected in series through an input valve to the upper part of a pressurized tank for transporting powder and granule materials. When the remaining amount of the powder or granule is reduced, the powder or granule in the powder or granule supply tank is charged into the pressurized tank for transporting powder or granule through the input valve, and the powder is discharged from the pressurized tank for transporting the powder or granule. This invention relates to a serial high-pressure continuous transportation method for powder and granular materials that continuously transports granular materials.

増加させて粉粒体の高圧連続輸送を行なうものである。This high-pressure continuous transport method for powder and granules is applied when continuously transporting powder and granules from a single powder and granule transport tank, and is normally used to transport powder and granules in a powder and granule transport tank. However, when the amount of remaining powder or granules is below the Pir4N value, the powder or granules are not transported, and instead of being transported, the powder or granules are inputted from the powder supply tank in an amount greater than the transported amount, and the powder or granules in the transport tank are This is to increase the filling capacity of the powder body and to carry out high-pressure continuous transportation of powder and granular material.

。In the high-pressure transportation method, during the transportation of powder and granules, the pressure inside the transportation pressurized tank is controlled to a high pressure at a fixed value in order to ensure constant transportability of the powder and granules. We try to avoid fluctuations in the pressurized gas supply pipe that supplies the tank as much as possible.

粉粒体の定量輸送を確保できない重大な欠点があった。However, in the series-type high-pressure continuous transport method for powder and granular material as described above, when the remaining amount of powder and granular material in the pressurized transport tank decreases, the pressure in the supply tank is maintained at the same pressure as the pressure inside the pressurized transport tank. Since the powder and granular materials are charged, the flow rate of pressurized gas to the pressurized tank for transportation fluctuates during this charge.
There was a serious drawback that it was not possible to ensure quantitative transportation of powder and granular materials.

This is done by operating a valve to control the pressure inside the pressurized tank for transportation at a fixed value. ``Examples of the inventive method will be described below with reference to the drawings.''
